` 1 Claim.

in my mentioned patent, whereby the same canv be economically formedfrom' steel.

A further important object of my invention is to provide novel means forhingedly connecting the side sections of the drawbar with the centralmain section thereof and to brace the drawbar in a novel manner, wherebyundue strain on the hinges will be eliminated.

With these and other objects in view, the invention consists in thenovel construction, arrangement, and formation of parts, as will behereinafter more specifically described, claimed,

and illustrated in the accompanying drawing, in-

which drawing:

Figure lis a fragmentary, top, plan view showing my improved all-steeldrawbar connected with a sectional harrow.

Figure 2 is a. detail sectional view taken o n the line 2-2 of Figure 1,looking in the direction of the arrows, illustrating the means forbracing the drawbar and for hingedly connecting sections thereoftogether.

. Figure 3 is a fragmentary, detail, sectional viewtaken on the line 3-3of Figure 1, looking in the direction of the arrows, illustrating one ofthe hinges.

Figure 4 is a view similarto Figure 3, but showing one section of thedrawbar folded over the central adjacent section.

Referring to the drawing in detail, wherein similar reference charactersdesignate corresponding parts throughout the severalviews, the letter Bgenerally indicates my improved drawbar for a sectional harrow H. Theharrow H forms no part of my present invention and can be of the generaltype illustrated in my prior patent.

As shown, the harrow H includes arcenltral section 5 and side sections 6and 1. The forward ends of the sections 5, 6, and 1 are provided witheyes 8 for receiving coupling hooks or the like 9 carried by the drawbarB. k

My novel drawbar B is of an al1-steel construction, and the sameembodies a main section I0 md sid sections II and I2. These sections I0,55

I'I, and I2 can be formed from steel pipe ofthe desired length, .and theadjacent ends of the sections are hingedly connected together. Thus, themeeting ends of the sections each have welded thereto upwardly extendinghinge leaves I3, and the adjacent hinge leaves are arranged inoverlapping relation and are connected together by hinge bolts I4. Thus,the sections II and I2 can be folded over lthe section I0, and,obviously, the side sections 6 and 'I of the lharrow can be folded withthe side sections ofthe drawbar over the central harrow section 5.

Rigidly welded to the front face ofthe main drawbar section I0 adjacentthe hinges are forwardly extending metal pull bars I5, and these pullbars are arranged in parallel relation and terminate in right-angularlyextending, verti- :ally disposed apertured ears I6. Welded tothe upperface of the pull'bars I5 and to the inner faces of the ears I6 areinwardly directed, diagonally extending, metal brace bars I 1, and thesebrace bars have their inner ends welded to the front face of the mainsection I0 of the drawbar. By referring to Figure 1, it can be Vseenthat the inner ends of the brace bars are spaced a considerable distancefrom the hinges, and the brace bars in conjunction with the pull barsand parts of the main drawbar section. I0 form open, rugged, triangularbrace frames.

The brace bars I1 adjacent the apertured ears I6 have welded orotherwise secured Vthereto eyes I9, which receive the looped ends ofpull reds 20. The inner ends of the 13,1111 rods 20 are connected by alink 2|, and this link or'ring has connected therewith -the evener bar`of a doubletree 22 for permitting the connection of draft animals withthe drawbar.

Firmly welded to the front faces of the side sections Il and I2 of thedrawbar intermediate 'the ends thereof are'metal connecting straps 23.

These straps extend inwardly and forwardly toward the forward terminalsof the pull bars I5 and terminate inv hinge hooks 24, which extendthrough the apertured ears I6 of said pull bars.

As the hinges and the hooks`24 are substantially` from tubular lengthsof material, with their adjacent ends normally in abutting relation,overlapping hinge leaves rigidly secured to the upper faces of theadjacent end s of said sections. hinge bolts pivotally connecting theoverlapping leaves together, forwardly projecting pull bars rigidly'secured to the-ends of the main drawbar section. the forward ends ofsaid pull bars terminating in apertured ears. diagonally extending bracebars rigidly secured to the ends of the pull bars and to the mainsection inwardly of its terminals, pull links connected with the bracebars. inwardly directed 1straps rigidly secured to the side drawbarsections intermediate 4the ends thereof, and hooks formed on said strapsreceived inlsaid apertured ears.
